Title: The new digital mathematics of the millennium
Authors: Kyritsis, Konstantinos
Abstract: This project is under the next philosophical principles
1) Consciousness has the experience of the infinite.
2) But the physical material world is finite.
3) Therefore mathematical models in their ontology should contain only finite entities and should not involve the infinite at all which is a phenomenological abstraction. In digital mathematics we may have the concepts of seemingly infinite sets (or seemingly infinitesimal numbers) but they are essentially finite sets or numbers with finite decimal representation.
These principles allow for an alternative and more realistic universe of mathematics, directly usable in artificial intelligence of computers. The development of digital mathematics is somehow more elaborate in the definitions but radically easier in the proofs compared to classical mathematics. It is certainly not equivalent to the classical mathematics. But here we give emphasis only to the theorems that are very similar and very familiar with corresponding to classical mathematics.
The previous principles require a rewriting of the classical axiomatic systems to those of
1) the natural digital numbers,
2) the digital 1st and 2nd order formal logic,
3) the digital set theory,
4) the digital real numbers,
5) the digital differential and integral calculus,
6) the digital Euclidean axiomatic continuous geometry
etc.
In the next two papers we present the digital real numbers with the digital differential and integral calculus and the digital axiomatic continuous Euclidean geometry, where all sets of points (visible or invisible) or numbers are finite sets of points and numbers with finite decimal representation.
Our perception and experience of the reality, depends on the system of beliefs that we have. In mathematics, the system of spiritual beliefs is nothing else than the axioms of the axiomatic systems that we accept. The rest is the work of reasoning and acting.
For each of the two papers we give at its end a fictional philosophical or epistemological dialogue with the celebrated immortals of the classical mathematics (like Euclid, Pythagoras, Hilbert, Cantor, Gödel, Newton, Leibniz etc) where the reader can grasp in non-technical terns the main differences and the main advantages (or disadvantages) of the digital mathematics where all are finite compared to the classical mathematics which are based on the phenomenological abstraction of the infinite
The 2nd of the two papers on the digital but continuous axiomatic Euclidean geometry has already been published in the World Journal of Research and Review (WJRR)ISSN:2455-3956, Volume-5, Issue-4, October 2017 Pages 31-43Wed, 20 Feb 2019 00:00:00 GMThttp://cris.teiep.gr/jspui/handle/123456789/16842019-02-20T00:00:00ZThe influence of flexible working on unemployment: Evidence from the greek labor markethttp://cris.teiep.gr/jspui/handle/123456789/1683

Title: Public utilities privatizations in open economy: A literature review
Authors: Karamanis, Kostas; Triarchi, Eirini
Abstract: The purpose of this paper is to record important studies and to draw useful conclusions on the effects of structural changes in public utilities. As a case study the telecommunications markets will be analyzed, since in almost all developed and developing countries the telecommunication sector has experienced a transition process from a highly regulated stated –owned monopoly to a liberalized competitive market regime. In particular, the impacts of the privatization of the traditional organizations, introduction of competition and the establishment of an independent regulatory authority related to market performance indicators such as telephone penetration, amount of investments, prices and quality of service, employment and labor productivity, will be examined.Sun, 01 Jan 2017 00:00:00 GMThttp://cris.teiep.gr/jspui/handle/123456789/16812017-01-01T00:00:00ZEvaluation of leasing as a method of funding Investments in greek agribusiness sectorhttp://cris.teiep.gr/jspui/handle/123456789/1680
Title: Evaluation of leasing as a method of funding Investments in greek agribusiness sector
Authors: Zaridis, Apostolos D.; Karamanis, Kostas
Abstract: Funding for acquiring assets in Greek agribusiness sector is very common and supports Greek agribusiness SME's production. Purpose of this study is evaluation of leasing as a method of financing in order to acquire assets used directly in the production process of a business of secondary Greek agribusiness sector or even vertically integrated business. Thus, research was held in December of 2012, collecting proper data from Greek banking sector and considering Tax Legislation. Selection decision of practices financing in the event of such an investment should be made after taking into consideration several factors. Proper financial evaluation of future investment is necessary, while it's too necessary to be compared the financing choices that are given in Greece. Considering Tax Legislation, Banking Practices, and Law on Leasing, financing methods were compared in reference period. Avoiding generalizations, typical examples are given, showing that leasing preceded against borrowing, considering conditions prevailing in Greece at the time. But decision making for selection of financing method is affected by factors, which may lead to either correct or incorrect conclusions for firm's interests, if evaluation is not correct or there are personal interests of decision-makers in the administration. Consequently, incentives to use leasing for financing a business can be a lot, but quite important are ownership structure, nature of investment opportunities, business risk and tax status.(original abstract)Thu, 01 Jan 2015 00:00:00 GMThttp://cris.teiep.gr/jspui/handle/123456789/16802015-01-01T00:00:00Z
